Open the CIPO recordAbstract From the Canadian patent
A pressure-adherent silicone elastomer composition comprising a homogeneous mixture of a silicone pressure sensitive adhesive composition, a crosslinkable silicone elastomer composition and, optionally, a viscosity reducing agent. Specifically, the silicone pressure sensitive adhesive composition is a condensation product having a, plasticity of less than 200 mils of a benzene-soluble, resinous copolymer containing silicon-bonded hydroxyl radicals and consisting essentially of triorganosiloxy units of the formula R3SiO1/2 and tetrafunctionalsiloxy units of the formula SiO4/2 in a ratio of about 0.6 to 0.9 triorganosiloxy units for each tetrafunctionalsiloxy unit present in the copolymer and …
